🚆 Alpine Railway: Gradient, Adhesion Limit, Power Climb and Braking (2D)

Side view of a train on an alpine gradient, with bars showing the tractive effort that adhesion and power allow against the resistance and the pull of the slope. Set train mass, power, driven weight, wheel-rail friction, gradient and speed limit, and see the steady climbing speed, the steepest slope the train can start on and the braking distance. Time-stepped motion is checked against closed forms, with four in-page numerical checks.
